Our homelessness non profit Tap London has contactless payment units across London that collect £3 donations for youth homeless charities.
We have a live tally iframe that sits on our front page. We are now accepting online donations too. We would like the live tally on our front page to include the online donations as well.
The company processing the online payments said they could provide webhooks and we could take care of the storage and tabulation and adding it to the live tally.
Could anybody advise me on the best way to set this up?
