I’m trying to create a connection to Google Slides and am receiving the “Error 400: redirect_uri_mismatch”. I’ve followed the instructions from previous posts to edit my connection to enable all of the relevant APIs, confirmed that the correct scopes have been selected, and updated the redirect URIs to include every variation listed in the different documents. Regardless, I’m still receiving this error and not sure what to do.
Welcome to the Make community!
Follow this main guide on how to set up a custom OAuth 2.0 custom app in Make.
Provided below are additional supplementary instructions in case the above isn’t clear enough.
Search for the relevant Google API here: https://console.cloud.google.com/apis/library
Go to each API page that you want to use, end click “Enable”
Usually you’ll want to enable at least Drive (includes Docs/Sheets) and Gmail.
Direct Link: https://console.cloud.google.com/apis/credentials
Here are some commonly-needed redirect URIs you need for your Google Cloud Console OAuth app. If you set these up, you can reuse the same GCP app for other Google apps and modules on Make.
https://www.make.com/oauth/cb/google
https://www.make.com/oauth/cb/google-custom
https://www.make.com/oauth/cb/google-restricted
https://www.make.com/oauth/cb/google-cloud-speech
https://www.make.com/oauth/cb/youtube
https://www.make.com/oauth/cb/oauth2
https://www.integromat.com/oauth/cb/oauth2
Note: Once you’ve set these up, you can use/reuse the same Make connection for all the supported Google apps & modules on Make - you’ll only have to enable the APIs for your custom app.
Direct Link: https://console.cloud.google.com/apis/credentials/consent/edit
Insert make.com and integromat.com
Fill in other required fields
Click “Save and Continue”.
Click “Add or Remove Scopes”
Select 100 “Rows per page”, for each page, check all the rows, OR
Manually type in the scopes you need
Click “Update” at the bottom
At the last step/page, click “BACK TO DASHBOARD” instead of “Prepare for Verification”
You will need to set your OAuth application to “Production”, otherwise the credentials expire very frequently.
To do this, go back to “OAuth consent screen”
Then click the “PUBLISH APP” button
Then click the “CONFIRM” button
You can find the Client ID and Client Secret in the OAuth2 app you created in GCP, on the right-hand side of where you inserted the callback URLs in step 2:
Insert the GCP app client ID and secret here BEFORE clicking “Sign in”
(Gmail example)
OR,
You need a “Authorize Parameters” key of redirect_uri with the above Make OAuth2 callback URL.
Hope this helps! Let me know if there are any further questions or issues.
