POST /api/v1/bulk-bonus-payments/{id}/pay
/api/v1/submissions/bonus-payments
Set up bonus payments to one or more participants/submissions in a study.
| You need the study id, the participant | submission ids and the request in CSV format. |
The csv_bonuses field needs to be structured in the format of either:
<participant_id>,<amount>\n.<submission_id>,<amount>\n.Setting up a bonus payment does not actually pay them, to do so check /api/v1/bulk-bonus-payments/{id}/pay/
The submission and participant IDs need to have taken part in the study in order for this call to be successful.
If not, you will get a “400” HTTP response back, which explains which IDs are incorrect.

Duplicating a study can save a lot of time and effort compared to creating a new study from scratch, since all of the information and data from the original study will be carried over to the new study. Additionally, duplicating a study can help ensure that the new study is set up consistently with the original, reducing the risk of errors or inconsistencies.
To prevent repeat participation, a block list containing the original study will be added to the duplicated study’s filters unless block_previous_participants is set to false in the request body.

Transition a submission to APPROVED or REJECTED. Once the status is changed, it can not be restored to its previous value.
We strongly recommend that, when giving approval to a submission through the API, you first observe the submission.status.change
event for a status transition to
AWAITING_REVIEW before making the approval request. Our system is currently unable to process approvals before this transition.
Note this endpoint is idempotent, so if you make the same request twice, the second request will be ignored.

Date values should be provided as a string in ISO 8601 format.\n\nLeaving a value as null will result in that bound being set to the lowest or highest possible value, depending on whether it is the upper or lower bound."
