Go into your GoProposal site, then under Settings > Integrations you should see the following:

Firstly it’ll need a "Senta Access Key". In a separate browser tab go into your Senta workspace, and click on Settings > Users > Add integration 

Call it something like "GoProposal"

Then "Generate API key":

Copy and paste that key back into into GoProposal:

Finally, fill in your Senta “subdomain”, i.e. the address of your Senta workspace without the “https://” or the “.senta.co”

The next bit of the setup is to configure which Line items in GoProposal will match which Services in Senta

Alternatively Proposal types in GoProposal can be set up to match a bundle of Services in Senta

You can add multiple Senta services to each Proposal type.
