Pass-through

MeisterTask 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 MeisterTask. Then send them their link.

Your client connects

They sign in with MeisterTask and approve.

Find the endpoint

Pick the call from MeisterTask's own API docs. Your path is everything after https://www.meistertask.com/api.

Send it through Operate As

Use the client's ID, the service key meistertask 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-.../meistertask/projects" \
  -H "Authorization: Bearer $OPERATE_AS_API_KEY"

curl "https://api.operate.as/v1/clients/6f1c2a7e-.../meistertask/projects" \  -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

Operate As renews the sign-in before it runs out and checks it daily. If MeisterTask refuses to renew it, the service shows Expired, you're alerted, and your client reconnects from the same link.

See Keeping access alive and Removing access.
