Software Localization API Documentation
Before You Begin
Prepare the access, development environment, source resource, and internationalization foundation required for a reliable first integration.
- An approved Stepes Software Localization API key
- Access to the assigned sandbox or production environment
- cURL, Postman, Node.js, Python, or another server-side development environment
- A supported structured software resource file
- A defined source locale and at least one target locale
- Permission to submit the selected software content
- A secure secrets-management process
- A stable application or project reference for reconciling API activity
Keep credentials server-side. Do not place API keys in browser-delivered JavaScript, mobile application packages, query strings, public repositories, screenshots, issue trackers, or application logs.
Prepare an Internationalized Resource
The API manages localization content; it does not replace software internationalization. Externalize user-facing strings, use stable keys, document variables and character limits, and confirm that your application can load locale-specific resources correctly.
Externalize Interface Text
Keep customer-facing content in supported resource files rather than hard-coded application strings.
Document Runtime Behavior
Identify placeholders, plural logic, grammatical role, visual constraints, and product terminology.
Test Locale Loading
Confirm that the application resolves locale-specific resources and regional formatting correctly.
Understand the Software Localization Resource Model
Software localization preserves the relationships among products, branches, resource files, translation keys, locale values, reviews, quality results, and releases.
A first implementation can begin with one workspace, one project, one branch, one resource file, and one target locale. Add repository mappings, parallel release branches, and broader workflow controls as your localization program grows.
Explore the Software Localization APIConfigure Your API Environment
Store the base URL and API key in secure environment variables so the same integration code can operate safely across assigned environments.
https://api.sandbox.stepes.com/v2https://api.stepes.com/v2export STEPES_BASE_URL="https://api.sandbox.stepes.com/v2"
export STEPES_API_KEY="YOUR_STEPES_API_KEY"$env:STEPES_BASE_URL = "https://api.sandbox.stepes.com/v2"
$env:STEPES_API_KEY = "YOUR_STEPES_API_KEY"Send the assigned API key in the Authorization header using the bearer scheme. Additional headers may apply for workspace context, idempotency, tracing, or operation-specific controls.
Review the API Reference for the required headers, schemas, responses, events, and error definitions for each operation.
Authenticate Your Application
Verify bearer authentication from a secure server-side environment, then confirm the assigned environment, accessible workspace, and effective permissions.
curl --request GET \
--url "$STEPES_BASE_URL/workspaces" \
--header "Authorization: Bearer $STEPES_API_KEY" \
--header "Accept: application/json"const response = await fetch(
`${process.env.STEPES_BASE_URL}/workspaces`,
{
headers: {
Authorization: `Bearer ${process.env.STEPES_API_KEY}`,
Accept: "application/json"
}
}
);
if (!response.ok) {
throw new Error(`Authentication check failed: ${response.status}`);
}
console.log(await response.json());import os
import requests
response = requests.get(
f'{os.environ["STEPES_BASE_URL"]}/workspaces',
headers={
"Authorization": f'Bearer {os.environ["STEPES_API_KEY"]}',
"Accept": "application/json",
},
timeout=30,
)
response.raise_for_status()
print(response.json())Confirm the Returned Context
- Organization and workspace
- Environment and API version
- Integration identity
- Assigned permissions
- Available software-localization capabilities
Authentication Troubleshooting
Confirm the API key, bearer header, base URL, and target environment. Use the returned Stepes-Request-Id when troubleshooting authentication or permission failures, and rotate any key that may have been exposed.
Create a Software Localization Project
Define the product, source locale, target locales, resource format, workflow, language assets, review requirements, quality gates, and delivery behavior.
Example project configuration. Use the operation path, field names, permissions, and validation rules provided for your assigned API version.

"name": "Account Security",
"clientReference": "account-security-localization",
"sourceLocale": "en-US",
"targetLocales": ["fr-FR"],

}
}Choose the Right Workflow
An internal diagnostic message, customer-facing navigation label, payment confirmation, legal notice, and medical warning carry different levels of visibility and risk. Configure translation and review based on content type, technical complexity, target market, regulatory importance, and release requirements.
AI Translation
Use controlled automation for eligible internal, diagnostic, high-frequency, or lower-risk software content.
AI + Human Review
Combine speed with professional linguistic review for customer-facing interfaces, onboarding, settings, notifications, and support features.
Professional Translation
Route regulated, safety-sensitive, legal, medical, financial, or publication-critical content to qualified linguists.
Product Approval
Let designated stakeholders confirm terminology, functionality, market suitability, and product intent before release.
Use Translation Memory First
Reuse approved product language across platforms, modules, versions, and markets while preserving review history.
Explore Translation MemoryApply Approved Terminology
Protect product names, feature labels, technical vocabulary, regulated terms, and words that must remain untranslated.
Explore Terminology ManagementSynchronize a Resource File
Submit a complete source resource or synchronize only the new and updated content identified by your development workflow.

"account.security.reset_password_button": "Reset password",
"account.security.password_requirements": "Use at least {minCharacters} characters.",
"account.security.reset_password_success": "Password reset for {username}.",

Validate the Imported Resource
Review file format, encoding, duplicate keys, missing values, unsupported syntax, placeholders, plurals, locale compatibility, character limits, and resource integrity before localization begins.
Do not ignore import warnings. A warning may not block synchronization, but it can still affect translation quality, build integrity, or runtime behavior.
Start and Monitor Localization
Submit the selected branch, resource, changed strings, and target locales to the configured translation, review, approval, and quality workflow.
Example localization request. Use the published operation, schema, permissions, status model, and event definitions for your assigned API version.

Monitor Status Responsibly
Polling can support an initial sandbox integration. Increase the interval between checks, respect rate limits, stop at documented terminal states, and handle locale-specific or partial completion without restarting successful work.
resource.file.importedResource synchronizedsource.string.changedReview routing startedtranslation.completedTarget locale translatedqa.issue.detectedPlaceholder mismatch flaggedtranslation.approvedProduct approval completebuild.generatedLocalized package readyProduction integrations should use signed webhooks for meaningful workflow events. Verify signatures against the unchanged raw request body, process every event idempotently, and expect duplicate, delayed, or out-of-order delivery.
Configure Webhooks and EventsReview Translation and Quality Results
A translation can be linguistically accurate and still create a software defect. Validate both language quality and technical integrity before generating a localized build.
Le mot de passe de {username} a été réinitialisé.The runtime value remains available to the application.
Le mot de passe de l’utilisateur a été réinitialisé.The target value removes the runtime placeholder and should not pass the release gate.
Placeholder Validation
Detect missing, added, renamed, reordered, or malformed runtime values.
Markup and Syntax
Protect HTML, XML, Markdown, escape sequences, ICU messages, and application-specific structures.
Plural Completeness
Confirm that target-language forms remain complete and technically valid.
Character Limits
Flag translations that exceed configured interface or device constraints.
Terminology
Apply approved product names, feature labels, technical vocabulary, and prohibited-term rules.
Locale Formats
Review numbers, dates, times, currencies, units, separators, and punctuation.
Encoding and Characters
Identify invalid encoding, corrupted characters, Unicode issues, and unsupported symbols.
RTL Readiness
Support bidirectional content and right-to-left testing workflows.
Generate and Retrieve the Localized Build
Compile approved locale values into a technically valid package for testing, integration, or deployment.
{
"account.security.reset_password_button": "Réinitialiser le mot de passe",
"account.security.password_requirements": "Utilisez au moins {minCharacters} caractères.",
"account.security.reset_password_success": "Le mot de passe de {username} a été réinitialisé.",
"account.security.two_factor_auth": "Authentification à deux facteurs"
}The output preserves source keys, runtime placeholders, resource syntax, locale mapping, and approved terminology. Before moving it into development, confirm the project, branch, source revision, resource format, approvals, quality results, and file integrity.
Return the Resource to Development
A direct integration can place the completed file in the expected locale directory. A connected workflow can commit the resource to a branch, create a pull request, trigger resource linting, build the localized application, and begin visual or functional localization testing.
Add Repository Automation
Synchronize source resources, preserve branch mappings, and return approved localized files through controlled commit or pull-request workflows.
Add Localization to CI/CD
Detect resource changes, enforce locale readiness and QA gates, retrieve approved builds, run tests, and continue deployment.
Supported Software Localization Formats
Localize structured resources across web, mobile, desktop, cloud, embedded, gaming, and cross-platform development environments.
Production Readiness Checklist
Complete a structured security, reliability, workflow, quality, webhook, monitoring, and delivery review before moving automation into production.
- Store the assigned API key in an approved secrets manager.
- Separate sandbox and production credentials.
- Apply least-privilege access and use an integration identity for production automation.
- Document API-key rotation and revocation procedures.
- Use stable client references and documented idempotency controls.
- Configure timeouts, bounded retries, and request tracing.
- Validate source resources, stable keys, placeholders, plural structures, and source revisions.
- Reconcile every localized build with its project, branch, locale, and source version.
- Match translation and review rules to customer visibility, technical complexity, and risk.
- Associate the correct translation memory and terminology resources.
- Require the appropriate reviewers, approvers, and release gates.
- Handle partial locale completion intentionally rather than restarting completed work.
- Verify every webhook signature against the unchanged raw request body.
- Store event IDs and process events idempotently.
- Expect duplicate, delayed, and out-of-order delivery.
- Keep sensitive source and target content out of unnecessary logs.

Software Localization Testing ChecklistSoftware Localization API FAQ
Review common questions about software resource synchronization, continuous localization, quality assurance, review, repositories, and deployment automation.
A software localization API connects development systems directly to the workflows used to translate, review, validate, and deliver localized product content. It manages software-specific objects such as resource files, translation keys, branches, locales, contextual metadata, review states, quality results, and localized builds.
The Translation API supports broad translation automation for text, documents, files, and managed projects. The Software Localization API is designed for recurring development cycles and preserves the relationships among software resources, keys, branches, placeholders, plural structures, reviews, and release-ready builds.
Yes. Change-based synchronization identifies added keys and modified source values while retaining eligible approved translations for unchanged content. Project rules determine whether affected translations are reused, reviewed, regenerated, or translated again.
Yes. Strings can include screenshots, developer comments, key names, source references, component information, character limits, placeholder definitions, and approved terminology so translators understand meaning, function, and interface location.
Yes. Stepes workflows can combine translation memory, terminology-guided AI translation, professional translation, post-editing, linguistic review, subject-matter validation, in-country review, product approval, and automated software quality assurance.
Yes. Teams can synchronize resources, preserve branch relationships, return approved localized files through controlled repository workflows, enforce quality gates, retrieve localized builds, run automated testing, and continue deployment.
Stepes can support professional translation, subject-matter review, terminology governance, automated QA, approval controls, role-based access, auditability, and controlled delivery. The workflow should be configured for the product, market, content risk, validation plan, and applicable requirements.
Stepes uses bearer API-key authentication for server-to-server integrations. Send the assigned API key in the Authorization header, keep it out of browser code, mobile packages, source control, and logs, and use separate credentials for sandbox and production.
The Stepes API Reference is the authoritative source for methods, paths, parameters, schemas, status codes, errors, event definitions, and integration conventions. Use the generated reference and machine-readable contracts when implementing production requests.
