Steps
Authenticate requests with an API token in the X-Api-Token header against a specific project ID
POST to the upload-a-file endpoint with the file content (base64), format, and language ISO code to queue an import; the import runs as a background Queued Process
Poll the returned process ID via the processes endpoint until status is finished before assuming keys/translations were created
Trigger a project export/download via the files endpoint, specifying target format and options (e.g., plural format, placeholder format), then poll its process and fetch the resulting bundle URL
Use the keys/translations endpoints directly for smaller, granular updates instead of a full file round-trip when only a few strings change
Known gotchas
Both upload and download are asynchronous background processes — the initial API response only returns a process ID, not the finished result, so callers must poll rather than assume synchronous completion
Export download URLs are time-limited (documented as valid for a number of months, not indefinitely), so pipelines should download promptly rather than caching the URL long-term
Format-specific export options (plural rules, placeholder syntax) must match what the consuming app framework expects, or merges will corrupt ICU/format-specific syntax on import back into the codebase
