Takpayment Merchant API

The rendered documentation did not load. Everything is in the specification itself:

openapi.yaml — import it into Postman with Import → File, or into Insomnia, Bruno, or anything else that reads OpenAPI. You get a working collection with every field, example and error already filled in.

In short: POST /v1/payments returns a url; send your customer there; when they return to your callback_url, call POST /v1/transactions/verifyTransaction and credit them when is_verified is true and is_checked is false.
