I’m developing an java backend service for a government agency which needs to publish to several accounts at the same time. I asked if this was possible here , and although it certainly seems like it is (here’s a similar question) for the life of me I can’t seem to figure out the correct instructions for the three-legged OAuth flow.
My question is, how do I, as it says on the first answer, “have each of the target accounts go through the sign-in with Twitter / three-legged OAuth flow to retrieve account secret keys for each of them” ? I’ve registered the app, and it is possible to publish from it into it’s associated developer twitter account, but I can’t seem to find a way to publish from that app into a new twitter account (@Igorpoitras_ES). How do I, as owner of IgorPoitras_ES, allow the app to publish in its behalf?
