Inventory Upload problems. New API Token?

Our inventory had been uploading automatically to our third party website provider. It suddenly stopped on Monday and has not uploaded since. As I look under the Client API access section all of our keys have been revoked. The support directed us to query this forum for a new access token. Please help.

Hi,
The developer needs to send a link for you to authenticate the integration and request for a Temporary Token. This Temporary Token can then be exchanged for an Access Token.
The steps are described here:

Thank you for your response. I am still a little unsure what the next step is. The integration team sent us a link that authorizes an access token. How do i get the Lightspeed side of things going. The token disappears and our inventory is still not uploading.

I'm guessing you already have a API client so you can go to step 2.
