GitHub API: List a users teams within an organization - github

Question

In GitHub when viewing my organization's user list I'm able to see how many teams a user is a member of.
Clicking on this count shows me which teams a user is in, putting me on the following page:
https://github.com/orgs/my-org/teams?query=%40username
However, I'm trying to achieve the same functionality via the GitHub API, but I've been unable to find an endpoint that lists what teams (within an organization) a user is currently a member of.
One workaround is to loop through all the teams in an organization and get their members list, but this can quickly go through my rate limit, so to be able to do this in one request would be useful.

Answer 1

You can do this with GraphQL API v4 filtering users in teams within an organization with userLogins :
{
organization(login: "my-org") {
teams(first: 100, userLogins: ["johndoe"]) {
totalCount
edges {
node {
name
description
}
}
}
}
}
which gives for instance :
{
"data": {
"organization": {
"teams": {
"totalCount": 2,
"edges": [
{
"node": {
"name": "Employees",
"description": "org employees"
}
},
{
"node": {
"name": "Developers",
"description": "active developers"
}
}
]
}
}
}
}

Unfortunately, GitHub does not yet provide a way to do this.
At the moment, like you suggested, you would have to loop through each team in the organization to get all members within each one, then you would need to loop through all users, and check if the users are members of those teams.
You can increase your rate limit if you use an API token, but the solution is still lousy if you have a large organization.

Heads up!
Providing an invalid/unknown "userLogin" sometimes results in all teams being returned.
Perhaps me doing something wrong, but I opened a ticket with GH about this, so lets see:
