Query the '/v1/customers?email=' with email that contains '+' sign

Question

Hi Team,I integrated the backend with Customer.io and it’s working fine except for some corner cases.We have some customers with non-standard emails - their emails contain a ‘+’ sign.The API, which I’m using in the backend, https://api.customer.io/v1/customers?email= doesn’t retrieve existing customers.I’ve tried to apply encoding to the URI, and even partially encoding applied only to the ‘+’ sign, but the result was not successful.Examples: test+test@test.comtest%2Btest%40test.com test%2Btest@test.comThe interface the customer accessible via https://fly.customer.io/workspaces/<workspace_id>/journeys/people?email=test%2Btest%40test.comand the email is fully encoded.I hope we soon find a solution,Thank you

Hi Alexey,This is Byron from the technical support team. Great question! I did a little testing using cURL and Postman and was able to retrieve results from both by encoding the `+` symbol in the request with `%2B`. I see you mentioned that you tried that without success, so we may need a little more information about the full request you sent.cURL:curl --request GET \  --url 'https://api.customer.io/v1/customers?email=byron%2Btest@customer.io' \  --header 'Authorization: Bearer <myToken>'Returns:{"results":[{"email":"byron+test@customer.io","id":"testid","cio_id":"f8e50600fee501ffe501"}]Postman:GEThttps://api.customer.io/v1/customers?email=byron%2Btest@customer.ioReturns:{  "results": [   {    "email": "byron+test@customer.io",    "id": "testid",    "cio_id": "f8e50643443201ffe501"   }  ] }I also tested encoding `@` to `%40` and that also worked for both cURL and Postman.
