I’m trying to create a script that can create tasks for me and set their custom fields. So far I figured out that my project ID is 727740646475748. If I call GET /projects/727740646475748, I find that my custom field ID 727729591481443 is and value ID is 727729591481447. Full json @ { "data": { "i…

(can you use the editor to format your code please? thanks :+1:)

I didn’t see a format code option, so I just left it. I also can’t seem to find an edit button, can I even edit posts? I’m new here.

Indeed you can’t when you are new member :slight_smile:

Documentation says: SETTING CUSTOM FIELD VALUES Custom fields are set with PUT requests similarly to setting other fields on tasks; the format of the request is to set the id to the new value. That is, custom_fields:{custom_field_id:custom_field_value} but looks like you are setting custom_fields …

@Floris_Thijssen Try following the syntax shown in this post: [image] Api & Custom Fields Developers & API Hey all, catching back up on backlog here. @Phil_Seeman It’s not well documented (I’ll create a follow up task to fix this) but indexing into arrays using form data…

I tried curl --request PUT -H "authorization: Bearer SNIP" https://app.asana.com/api/1.0/tasks/1125479699210021 --data-urlencode "custom_fields[727740646475736]=1109215504501105" And it gave me {"errors":[{"message":"custom_fields: Value cannot be an array: []","help":"For more information on API…

Ah wait, I think there’s a typo in what was suggested - I think it should be custom_field singular. In other words, try: curl --request PUT -H "authorization: Bearer SNIP" https://app.asana.com/api/1.0/tasks/1125479699210021 --data-urlencode "custom_field[727740646475736]=1109215504501105"

curl --request PUT -H "authorization: Bearer SNIP" https://app.asana.com/api/1.0/tasks/1125479699210021 --data-urlencode "custom_fields[727740646475736]=1109215504501105" Returns the JSON of the task, but the task itself isn’t getting changed. Output: { "data": { "assignee": { "gid": "69546205009…

Arghh, just tried it myself and I get the same result - it returns the task as if it worked but the custom field value is not changed. @Joe_Trollo @Jeff_Schneider @Matt_Bramlage @Ross_Grambo Any ideas here, guys, on what the proper syntax is to update a task’s custom field value via curl?

It works for me if I use: curl -X PUT https://app.asana.com/api/1.0/tasks/<task-id> -H 'Authorization: Bearer <pat>' -H "Content-Type: application/json" -d '{"data":{"custom_fields":{"<custom-field-id>":"It worked!"}}}' Does this work for you?
