Пытаюсь привязать платёжную систему Square

Пытаюсь привязать платежную систему Square.

Ввожу команду в терминал:

curl --request POST https://connect.squareupsandbox.com/v2/payments --header "Content-Type: application/json" --header "Authorization: Bearer EAAAEFFk7XqFJ4PBhPD8lBN4NsEWZegWYaD_Qo07uBxrsLHm0rFo38VFYqFL0bmF" --header "Accept: application/json"  --data '{ "idempotency_key": "ae7dabe6-2aec-42ff-b868-473cbeb8f847","amount_money": { "amount": 100,"currency": "USD"}, "source_id": "cnon:CBESEAHOhAS6638Hf9htX8WldY4"}'

Выдает ошибку:

{"errors": [{"code": "BAD_REQUEST","detail": "Expected \"{\" (line 1, character
1)","category": "INVALID_REQUEST_ERROR"}]}
curl: (3) URL using bad/illegal format or missing URL
curl: (3) URL using bad/illegal format or missing URL
curl: (3) unmatched brace in URL position 1:
{

Что можно сделать?
