Basis Theory uses API keys to allow access to the API.

Basis Theory requires the API key to be included in all API requests to the server in a header that looks like the following:

BT-API-KEY: key_N88mVGsp3sCXkykyN2EFED

You must replace key_N88mVGsp3sCXkykyN2EFED with your API key supplied when you created an Application.


curl "" \
-H "BT-API-KEY: key_N88mVGsp3sCXkykyN2EFED"
