# Resource owner password credentials flow

Warning

These will be the only supported endpoints after June 1st 2025. If you are using the old/legacy endpoints, we strongly recommend that you integrate with the new endpoints described here as soon as possible.

# Introduction

If the external system or application does not require user interaction for authentication and can securely store the user's username and password, the Resource Owner Password Credentials (ROPC) Flow can be used to obtain an access token.

In this flow, the user's credentials are sent directly to the authorization server, which then issues an access token and a refresh token.

# Obtaining an access token

To obtain a new access_token, the following URL should be used:

https://sso.pageroonline.com/oauth/v2/oauth-token

Request Method: POST

Required parameters in application/x-www-form-urlencoded:

Parameter	Description
`grant_type`	Must be `password`.
`username`	The username of a Pagero Online user to authorize.
`password`	The password of a Pagero Online user to authorize.
`client_id`*	The client ID.
`client_secret`*	The client secret.

Required headers (if not client_id and client_secret provided in the body):

Header	Description
`Authorization`	Authorization header for basic authorization, where the user should be the client id and password should be the client secret.

# Example with header option

Example with curl
curl https://sso.pageroonline.com/oauth/v2/oauth-token \
  -d grant_type=password \
  -d username=<username> \
  -d password=<password> \
  --user 'client_id:client_secret'

The response will contain a JSON body that looks like this:

{
  "token_type": "bearer",
  "access_token": "_0XBPWQQ_755ee1db-08e1-46a5-a121-538d37e5571d",
  "refresh_token": "_1XBPWQQ_d88969ce-25dc-40af-a558-fc647632d610",
  "scope": "",
  "expires_in": 600
}

Important

The refresh token is issued with a rolling lifetime of three years, allowing it to generate new access tokens continuously within this period. After three years, user authentication will be required to obtain a new refresh token.

# Making an API request using an access token

When making an API request, the access_token should be provided in an Authentication header as a bearer token.

# Example

Example with curl
curl https://api.pageroonline.com/someresource \
  -H 'Authorization: Bearer _0XBPWQQ_755ee1db-08e1-46a5-a121-538d37e5571d'
