This endpoint re-runs an application that has already been run through Alloy. It will be run through the currently active version of the Journey, and will default to re-using the same payload as the original, but does allow for the user to optionally alter that original payload.

The options for altering are the following:

• Edit any of the payload information for any of the entities in the application by including, within an object in the entities array, the entity_token of the entity to be altered. Include any number of fields to be altered. Assign a value of null for any field you want to exclude.
• Add any number of new entities to the application by including new entity objects in the payload.
• Delete entire entities by putting these entity tokens to be deleted into an array called exclude_entity_tokens (at least one entity must remain).

Any of the below headers used with the original application will also be used here. To change the value of the header, include the updated value with this request.
