Find this guide below on how to use Indeed Sponsored directly in Occupop:
Integrate your Indeed-sponsored account. To do this, you will need to go to Settings > Integrations > Indeed. Select "Login with Indeed". If you do not have an account set up with Indeed, it is recommended you create this directly with Indeed.
Follow the steps on the screen to enable the Occupop Sponsorship API. Select allow to proceed further. Select your employer account.
Follow the guidelines of step one again. Select Indeed to take a look if the integration has been successful.
Select Account settings on the right-hand side, this will open your Indeed employer account. Ensure you have a payment method set up in order to sponsor roles via the integration.
When posting/Editing a job, select "Job Boards". In this section, you will need to locate Indeed under the "Sponsored Boards" section. Enable this option. Select the campaign start & end date as well as the budget you wish to apply to this campaign. This will be billed to the currency the account is currently set up in.
Select Save & Back or publish, this will then communicate the sponsored role to Indeed once the account is set up correctly.
Once the campaign is set up, there will be an option to view the campaign stats. To access this, you will need to edit the role, go to "job boards" and you will see the option to view campaign stats on the Indeed Sponsored option.
