Hi Ronen,
Thanks for reaching out. In general, you can expect the API to be return the result immediately. However, for some longer running processes (e.g.
uploading click conversions), there will certainly be delay in retrieving that data (e.g. conversions
reporting).
Please note that the AdWords API will sunset in April 2021. Additionally, any developer tokens granted recently will only be given access to the new
Ads API.
Regards,
Matt
