Hi everyone,

I want to use the Nintex API to create multiple users at once.

I am using the Create User endpoint: POST /usermanagement/v1/tenants/{tenantId}/users

However, I cannot get it to work. I keep getting this error when I try:

JSON

{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.4",
  "title": "Forbidden",
  "status": 403,
  "detail": "Forbidden",
  "instance": "/tenants"
}

 

 i have provided the token that is global administrator role. Which it still not allow to create.

 

I have a questions:

Is there anyone use different method to batch create Nintex Workflow Users?

 

Thank you for your help!

Hi ​@yonghua.poh,

Can you provide a link to the API documentation you are using?
The reason I ask is that to create users in Nintex Workflow Cloud, the endpoint looks like: 

https://us.nintex.io/tenants/v1/users

Hi ​@yonghua.poh 

Make sure your Authorization header is configured like this:

Authorization: Bearer YOUR_TOKEN_HERE

If you left the Bearer prefix out of your token it would throw an error like this.

Hi ​@yonghua.poh,

To answer your other question about the best way to batch-create users. The best way is to configure SSO for the tenant. That way, any user who logs in automatically gets added to the tenant with the Participant role.
