Service	Key	Base URL
Finix	`finix`	`https://finix.live-payments-api.com`

Your client also types their username (Your Finix API username, starting US).

Connecting

Your client makes a Password in their Finix settings and pastes it on their link. Operate As tries it with Finix before saving it, and stores it encrypted. See Services connected with an API key.

Pass-through

Finix has no ready-made tools yet. Call any endpoint of its API through Operate As instead, with the client's access attached.

Add the client

In Clients, add your client and select Finix. Then send them their link.

Your client connects

They paste a Password from their Finix settings.

Find the endpoint

Pick the call from Finix's own API docs. Your path is everything after https://finix.live-payments-api.com.

Send it through Operate As

Use the client's ID, the service key finix and that path. Your Operate As key goes in Authorization; the client's access is added for you.

See Pass-through requests for the full request and response format.

Call any endpoint

curl "https://api.operate.as/v1/clients/6f1c2a7e-.../finix/merchants" \
  -H "Authorization: Bearer $OPERATE_AS_API_KEY"

curl "https://api.operate.as/v1/clients/6f1c2a7e-.../finix/merchants" \  -H "Authorization: Bearer $OPERATE_AS_API_KEY"

  },

}

When access ends

A key works until your client deletes it in Finix. They can paste a new one on the same link at any time, and your workflows carry on without changes.

See Keeping access alive and Removing access.

Calls answer, once the key is deleted
