Automate sending Discourse invite emails with Zapier

You could check with a get action event, if the user already has an account:

And if it’s the case, you run a path where you add this user to a group using a put action:

Awesome Krischan ! Thanks for your quick reply ! I’m trying it right now.

The Get part seems to work.

But I have an issue on the Put action :

1 / Can you tell me which Content-type do I have to put in header ?
(I guess I still add my API Username and API Key)

2/ On the URL of the Put Action, do I have to use the group ID (in number, like 110 in your example), or can I use the name I can get on the URL of the groupe ? (like “course-A” for example)

I tried to use the Name of the groupe (I don’t know where can I get the group ID) and it doesn’t seems to work.

Thanks ! :smiley:

Content type: multipart/form-data

No, I guess you have to use the group ID. You can get it eg. from the json file:


Awesome, with this content type + group ID, it seems to work !

Thanks for your quick help Krischan!


Hi Krischan ! :slight_smile:

Do you know if there is a way to notify the user by email to tell him he has been added to a group (with the Discourse API on Zapier) ?

I know it’s possible to tick a box, when we manually add email to a group on Discourse.

It could be good if I could trigger an email when my Zap is adding them to a new group.

Thanks !

Why don’t you send him a private message with a post event?


Thanks for your reply @Krischan !

Do you see a quicker way to notify the user ? (It’s ok if it’s a basic message from discourse, just like the one the user receives if I tick the checkbox “notify the users.”

Your solution is great, but as I have a lot of groups and automations, it could be great if I could just add “one” data type, for example to just “activate” the notification, instead of creating 30 new zap :stuck_out_tongue:

Sorry, I haven’t done this yet. But maybe this post can help you:


Thanks for your reply Krischan !
I will check that :slight_smile:


Hi guys :slight_smile:

Do you know if there is a way to Remove a member from a group, using the same logic explained upper ?

I noticed the API has a way to Delete group member : Discourse API Docs

But I’m not sure how to use it on Zapier :confused:

I need some help here. I’ve followed all the instruction and the link was created. However, the link is not assign to an e-mail. The e-mail field is empty and the user don’t receive any e-mail.
