I have created an integration in Magento 2.0 from the Magento Admin (System > Extensions > Integrations). Filled required fields like Name, Callback URL, Identity. But I am unable to activate it. Also when I click on activate it redirects to login page but does not come back to Integration page.
It gives warning as "Integration 'integration_name' has been sent for activation."
Can anybody let me know how much time it takes to activate the integration?
I think you have missed out something to insert into that integration form value page.
You need to enter Name and Email - then in callback URL just pass / (slash) then keep identity url blank.
Then from API select whatever the action you would like to apply - then click on save and try to activate it !
It will generate all 4 keys - consumer key , consumer secret , Access token and access token secret .
Refer this link for the same - https://devdocs.magento.com/guides/v2.2/get-started/authentication/gs-authentication.html
Hope it helps !
