The OpenAPI spec: wiring up a CRM, Postman or generated code
Beyond the readable reference on the API → Docs page, the whole API is also documented as a machine-readable spec file in the OpenAPI 3.1 standard — to import into Postman/Insomnia, wire up a CRM that understands OpenAPI, or generate a client automatically in any language.
GET https://vision.org.il/wa/api/v1.php?r=openapi.jsonThe address is public and needs no key (so you can explore and import before you create one), open to CORS, and returns standard JSON with every endpoint, parameter, request/response schema and error code — exactly as documented on the page itself, because both are generated from the same source. An X-WABOT-Version header on every response names the current API version.
To actually use the API you still need an API key in the Authorization header — the spec itself is open, but the calls it describes require authentication and are limited to Business and above, exactly like the rest of the API.
