Grant an integration limited programmatic access and verify a request against the current FixTech documentation.
Who this guide is for: owners and managers. Before making changes, make sure the correct establishment is selected.
Before you begin
- Sign in to the appropriate workspace and check the establishment name at the top of the page.
- Prepare the information you will enter. Payment and integration settings also require the provider's connection details.
- If an option is missing, check your plan and your role's permissions.
Setup steps
- Create an API client. Select the tenant, branches, expiry and only the required scopes.
- Store the secret. It is shown once; send it through a secure channel and keep it outside source code.
- Open the documentation. Use api.fixtech-dev.ru/docs and openapi.json for available routes and schemas.
- Test the requests. Send the bearer token, X-Correlation-ID and Idempotency-Key for state-changing operations, then retain the response log.

Check the result
The client cannot read another tenant or branch, a forbidden scope returns the unified error format, retrying with the same key does not create a second operation, and a revoked token stops working.
Troubleshooting
- Refresh the page and select the establishment again. Some data is only shown for the selected establishment.
- Check required fields, phone number format, dates and numeric values. Save errors appear on the right below the header.
- Do not create a duplicate just because a response is slow. Open the list first and check whether the record has already been created.
