JSON File-Based Token Persistence
A refresh token is a long-lived credential used in OAuth 2.0 flows that allows a developer to obtain new bearer tokens without requiring the user to re-authenticate. Developers use it to automate token lifecycle management, ensuring uninterrupted access to Concur APIs by programmatically replacing expiring access tokens. It is typically acquired alongside a bearer token during the initial token creation process and managed through refresh token automation workflows.
Tutorials that teach this
Prerequisites
- Concept Node.js Asynchronous Programming Patterns (Callbacks and Async Waterfall) The concept name provided is "undefined," which does not correspond to a identifiable SAP developer concept. Based on the available sources — which cover topics such as Node.js connectivity to SAP HANA, XS Advanced application development, Data Lake Relational Engine access, and Concur API token management — there is no concept that can be meaningfully defined under the label "undefined." Please provide a valid concept name so an accurate, source-grounded definition can be written.
- Concept Node.js Development in Cloud Foundry The concept name was not provided (marked as "undefined"), and the supplied source snippets do not contain enough substantive content — only titles and a brief fragment from S1 — to accurately define a specific SAP developer concept. A definition cannot be responsibly written without a valid concept name and sufficient grounding material from the sources.
- Concept Node.js Application Structure The concept name provided is "undefined," which does not correspond to a identifiable SAP developer concept. Based on the available sources — which cover topics such as Node.js applications on SAP HANA XS Advanced, Cloud Foundry deployment, approuter configuration, and Web Sockets — there is insufficient information to produce a grounded definition for a concept labeled "undefined."
