To use any of the above modules, you need to have a Wrike account and connect it to Integromat.
To connect your Wrike account to Integromat, follow the general instructions for Connecting to services. After you click the Continue button, a dialog box appears requesting your email and password. When you enter the requested information, you will be prompted to grant Integromat access to your Wrike data.
Here, allow access by clicking the Accept button. Afterwards, you will be redirected back to the Integromat administration page. Now you can continue and finish your scenario.
If you stop using an instant trigger, Integromat will automatically start to reject new incoming messages from the service. After three unsuccessful delivery attempts, the service itself will stop sending new notifications. So if you have a webhook that you do not use for a long time, it may happen that Wrike deactivates it and you will have to create a new one.
If you have multiple active scenarios which are running simultaneously and all of them are using the same connection, it may happen that some of those scenarios get stopped unexpectedly. Wrike uses a refresh-token based OAuth 2 connection. If this connection is shared by multiple scenarios and it's about to expire, one of the scenarios asks Wrike for refreshing the expiring token. Wrike returns a new access-token, but it also instantly invalidates the previous one, which can still be used with another currently running scenario. The running scenario tries to access Wrike with the old access-token, and it gets refused. That's how this error comes up. There's an easy fix for this problem - use a unique connection for each Wrike scenario, then the one scenario won't be affected with any other.
