* EthicsPortal application

Send the invitation email again and restart its 14-day validity. Allowed once every two minutes per invitation; sooner returns 429\. A personal token also needs its user to be a current administrator of the organisation.

## Authorizations

* **[personalToken](https://ethicsportal.eu/developers/api/#personaltoken)**  
members:write
* **[organizationToken](https://ethicsportal.eu/developers/api/#organizationtoken)**

## Parameters

### Path Parameters

**organization\_id**

required

string

Obfuscated organisation ID returned by identity.

**invitation\_id**

required

string

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters <= 255 characters /^\[\\x21-\\x7e\]+$/

Recommended on every POST. Retrying with the same key and the same request within 24 hours returns the first response (with Idempotent-Replayed: true) instead of acting twice. Only successful responses and validation errors are stored; any other outcome releases the key. Reusing a key with a different request returns 409 idempotency\_key\_reused; a retry while the first request is still running returns 409 idempotency\_key\_in\_progress. Keys are scoped to the token.
