File-Upload API requirements
In order to successfully publish a video via Swat.io, the uploaded file must meet the specifications required by the interface (API).
Note: Swat.io has no control over the requirements of the interface, as the APIs are provided and managed directly by the respective social medias. Accordingly, the requirements vary depending on the platform.
What happens in case of a non-compliant upload?
If you upload a file to Swat.io that does not meet the requirements of the API, you will see a blue notification banner directly in Publisher:
This notification is intended to inform you that the file does not meet the specifications of the respective platform. In most cases, it will also provide specific details on which file specifications need adjustment for the upload to be successful.

These guidelines will ensure that your content is optimized for mobile and desktop view on Facebook, maintaining a good balance between quality and loading time.
Important: Please make sure that your file upload meets all criteria mentioned above before starting the publication of the post. Otherwise, the video will be rejected by the API and will not be published. In this case a corresponding error message will appear in Swat.io's activity log.
Duration and processing time
The upload and publishing process on Facebook can take up to approx. 30 minutes or more, as the platform first internally processes the uploaded files.
Swat.io regularly checks if Threads has finished processing, then automatically publishes the video.
If no confirmation from Facebook is received within approx. 30 minutes, the upload will be marked as failed in the post's activity log.
Info: Once transferred to the social media platform, Swat.io no longer has any control over the upload process.
Note on Facebook' policies
Please also adhere to the Meta community-guidelines, to ensure your content does not violate any rules. In particular:
Do not violate any copyright without permission;
No glorification of violence or discriminating content;
No hate speech or other inappropriate content.
Violations of these guidelines may result in the removal of your video from the platform or restrictions of your account on the respective platform.
