API Documentation and Developer Portal Translation
Precise technical documentation for the developers who will use your product in any language.
Schedule a Brief Technical CallAPI documentation is the entry point for the developers who will integrate your product. If the translated reference contains ambiguities, terminology errors or incorrect code samples, the result is predictable: time wasted on debugging, avoidable support tickets and a negative perception of the product before it is even used in production.
M21Tech translates API documentation, SDK references, integration guides, changelogs and README files with linguists who understand concepts such as endpoints, payloads, rate limiting and OAuth authentication. We work with Markdown, OpenAPI/Swagger, JSDoc, Javadoc and proprietary formats. The goal is for the translated documentation to have the same level of precision and utility as the original.
API References and OpenAPI Specifications
We translate endpoint descriptions, parameters, responses and error messages in OpenAPI/Swagger specifications, keeping the YAML/JSON structure intact. Code samples are preserved with correct syntax and translated comments. Each translated reference is validated against the original schema to ensure technical integrity.
The linguists understand the difference between translatable text and technical identifiers (field names, data types, error codes). Only descriptive content is translated, eliminating the risk of altering functional elements of the specification.
SDK Documentation and Integration Guides
Integration guides, step-by-step tutorials and SDK documentation require absolute clarity. An ambiguous instruction can mean hours lost for the developer attempting to implement the integration. M21Tech linguists maintain the logical structure of the document, preserve cross-references and ensure that technical terms are consistent throughout the entire documentation.
We work with per-project glossaries, updated with each API version, so that terminology evolves in a controlled manner. Every delivery includes validation of internal links, code formatting and variable integrity.
Synchronisation with API Versions
API documentation changes frequently: new endpoints, deprecated parameters, behaviour changes. M21Tech uses translation memories and diff tracking to identify exactly what changed between versions and translate only the new or modified content.
This process reduces costs and turnaround times for incremental updates. Translation memories ensure that approved terminology remains consistent, even when different sections of the documentation are updated at different times.
Confidentiality and Supported Formats
All documentation is handled under NDA. Linguists work exclusively with content files, without access to source code. We support Markdown, reStructuredText, AsciiDoc, OpenAPI/Swagger (YAML and JSON), JSDoc, Javadoc, Doxygen and proprietary formats from platforms such as ReadMe, GitBook and Docusaurus.
File transfers are encrypted and access is restricted to the linguists assigned to the project. The process complies with ISO 17100 and GDPR requirements.
