--- layout: default title: Payment Handler description: Handle payment requests on behalf of a user --- DVMs providing this service are capable of handling recurring payments on behalf of users. The user for whom payments are handled can be defined by an optional `p` param # Input This job request takes no inputs. # Params (all optional) * `nwc` - A Nostr Wallet Connect * `p` - Pubkey of the target user for whom all `kind:7001`s should be handled * `relays` - A list of relays for `kind:7001` and `kind:7002` events. When a `nwc` param is provided, that NWC should be used to perform payments. When no `nwc` param is provided the DVM can use a "balance" or any other means it chooses (i.e. the user may have a custodial wallet with the provider funded via credit card payments, LN/ecash deposits, etc.) When a `p` param is provided, the DVM should handle all `kind:7001` events for the user with the provided pubkey. If no `p` tag is provided then the pubkey of the job request is used. # Output When the DVM stops handling payments for a user, it should publish a `kind:6906` event acknowledging of service to this job request. ```js { "content": "", "kind": 6906, "tags": [ [ "e", "<5906-event-job-request>" ], [ "p", "" ], ] } ``` # Feedback Job feedback is sent back the moment an event is scheduled. ```js { "content": nip04_encrypt(" [ \"status\", \"success\", \"Job has been scheduled, you can manage it on <....>\" ] "), "kind": 7000, "tags": [ [ "e", "<5905-event-job-request>" ], [ "p", "" ], [ "encrypted" ] ] } ``` # Example ## Request `pubkey-a` requesting DVM `dvm-pubkey` to begin handling `pubkey-b`'s recurring payments. ```js { "content": nip04_encrypt(" [ \"param\", \"nwc\", \"nostr+walletconnect://....\" ], [ \"param\", \"p\", \"\" ] "), "kind": 5906, "pubkey": "", "tags": [ [ "p", "" ], [ "encrypted" ] ] } ``` Upon reception of this request, the DVM should ```js { "content": nip04_encrypt(" [ \"param\", \"nwc\", \"nostr+walletconnect://....\" ], [ \"param\", \"p\", \"\" ] "), "kind": 5906, "pubkey": "", "tags": [ [ "p", "" ], [ "encrypted" ] ] } ``` ### Feedback A feedback ## Desponse ```json { "content": "", "kind": 6900, "tags": [ [ "p", "" ], [ "e", "" ] ] } ```
