What Is the Base URI?

The Base URI (also known as the Instance URL) is the domain where the SAP Concur entity resides. You must specify which location you are trying to work with by making a change to the end point declaration before you make your API call.

There will be a different domain for each of the following locations:

  • Production in the North America data center, EMEA data center, China data center, and PSCC data center.
  • Implementation (copy of the production environment not available for all clients) in the North America data center and EMEA data center.

Production

SAP Concur customer entities are hosted in various locations based on the client location, government regulations, and other special requirements. As a result, the correct Base URI must be used to reach a particular entity.

Data Center Environment Base URI Description
US Production https://us.api.concursolutions.com Default for all API calls (Optionally request certs)
US Production https://www-us.api.concursolutions.com Default for all API calls (Does not request certs)
EMEA Production https://emea.api.concursolutions.com Default for all API calls (Optionally request certs)
EMEA Production https://www-emea.api.concursolutions.com Default for all API calls (Does not request certs)
China Production https://cn.api.concurcdc.cn Default for all API calls (Optionally request certs)

PSCC Production https://usg.api.concursolutions.com Default for all API calls (Optionally request certs)

Implementation

The implementation base domains are used for implementation sites. An implementation site is a copy of an SAP Concur entity made from a backup of a client’s production site. This feature is only available for the Professional and Premium editions of SAP Concur products. Clients have the option to have a permanent implementation site established, contact your Client Executive or Account Manager for details.

Pre-2017 Legacy URIs (Deprecated)

The following base URIs have been used for APIs that are authenticating using the legacy authentication method. The new base URIs have been adapted to become backwards compatible with the legacy authentication methods. As such, these legacy base URIs should not be used unless necessary. JWT calls are not compatible with the legacy base URIs.

To migrate to the current authentication method, review these resources:

  • https://developer.concur.com/api-reference/authentication/migrationguide.html
  • https://developer.concur.com/api-reference/authentication/oauth2-migration-best-practices.html

These URIs support the current authentication and the previous authentication simultaneously.
