In our first few API requests, we already knew which ORCID iD to use (our own!) and we read/searched public information, which didn't require any permission from the user. In practice, you'll need to gather up iDs for researchers whose ORCID records you want to read, update, or associate with records in your own system AND get permission to take certain actions, like adding information to their ORCID records. In this section, we'll look at a few ways to get authenticated iDs and/or record access permission.

- 3. READ: public info: read.md

- 4. GET: authenticated iDs & permission: get.md

- 5. POST: an affiliation: post.md

- 6. PUT: Update an affiliation: put.md

- 7. DISPLAY: Presenting ORCID in your system: display.md

- 8. SEARCH: public info: search.md

- 9. RESOURCES: resources.md

- 10. Other methods for getting authorised iDs: Other_methods_for_getting_authorised_iDs.md
