API gotchas

When creating a new connection in Tenklo, you will need to add the appDetails, configuration parameter in the format MyApp ([email protected]), which will be appended to the request as a header: User-Agent: MyApp ([email protected]). This information will be used to get in touch if you’re doing something wrong(so the provider can warn you before you’re blocked) or something awesome (so the provider can congratulate you). Requests without a valid User-Agent header are rejected.
You will also need to add in your accountId connection configuration parameter.
