Our project is planning to reissue certificates for large amount of agents.
Do we have API on the certificates so we'll able to reissue on these agents at the same time without doing it manually (one by one)?
Currently there is no API for issuing certificates or renewing them.
This is expected in v5.5 of the manager.
For now, the only way is to filter the list to the Agents you need and choose to select all and then use Certificate management>Renew certificate.
You could also do similar in ADMIN>CERTIFICATES by select all and Renew.
