# Sign in with Microsoft (Gleap app)

`POST https://api.gleap.io/v3/mobile-auth/microsoft`

Sign in to the Gleap app with a Microsoft Entra access token for Gleap's API. The session lives as long as the Microsoft token; the app calls this again with a fresh token to renew it. 403 `microsoft_account_not_member` when no organisation of that tenant has this person as a member.

## Request body (`application/json`, required)

- `accessToken` (string, required): A Microsoft Entra access token for Gleap's API, from the app's Microsoft sign-in.

## Example request

```bash
curl --request POST \
  --url https://api.gleap.io/v3/mobile-auth/microsoft \
  --header 'Content-Type: application/json' \
  --data '{
  "accessToken": "<accessToken>"
}'
```
