Connecting

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

Check they're connected

curl https://api.operate.as/v1/me/clients \
  -H "Authorization: Bearer $OPERATE_AS_API_KEY"

curl https://api.operate.as/v1/me/clients \  -H "Authorization: Bearer $OPERATE_AS_API_KEY"

Pass-through

Paths continue from https://api.resend.com. 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-.../resend/..." \
  -H "Authorization: Bearer $OPERATE_AS_API_KEY"

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

Response

{
  "status": 200,
  "data": {
    "…": "the service's own response"
  },
  "encoding": "json"
}

{  "status": 200,  "data": {    "…": "the service's own response"  },  "encoding": "json"}

When access ends

A key works until your client deletes it in Resend. 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

{
  "status": 401,
  "data": {
    "…": "the service's own error"
  },
  "encoding": "json"
}

{  "status": 401,  "data": {    "…": "the service's own error"  },  "encoding": "json"}
