Search for your file in CSV format, the values must be separated by semicolons: ";". Description of the CSV file :

* 3 lines
* Line 1: a header that describes what each of the 3 columns corresponds to
* Line 2 and 3: the members of a cohort
* Column 1 UUID: Appconsent identifier of a user
* Column 2 external\_id (name defined by you): identifier of a user external to Appconsent
* Column 3 popname: name of the cohort

```
uuid;external_id_name;popname
9429e300-e33d-4590-83e8-e19bf611c1d6;external_id_1;population_name
7f03d94b-b8a1-4701-9b48-4e25a49f9645;external_id_2;population_name
```

You will then have to fill in the source Appkey (of the notice that is displayed by default on a web or app source) and fill in the destination Appkey (of the notice for the cohort). At any time you can stop a cohort from the Cohorts menu, and by clicking on the drop-down menu at the end of each line.
