Send envelope to another recipient - docusignapi

Question

I am trying to send a DocuSign envelope, that has already been sent to a customer (not signed yet), to another or a new customer. This is slightly different from resending the contract, but the same envelope is being resent to a new contact.
Is this possible? I have tried all sorts of things, like change the recipient details to new contact, add new sender to the existing recipient details.
The document is sent to the original sender fine, but to the new sender, the tab information is missing and the sign here tab is not there.

Answer 1

Replacing the original recipient :
The original recipient can be replaced with a new recipient using the UpdateEnvelopeRecipients api.
The original recipient will no longer have access to the envelope.
PUT /v2/accounts/{accountId}/envelopes/{envelopeId}/recipients
{
"signers": [
{
"recipientId": 1,
"email": "newsigner#acme.com",
"name": "New Signer",
}
]
}
Adding a new recipient: To add a new recipient in addition to the existing recipients, use the CreateEnvelopeRecipients api.
POST /v2/accounts/{accountId}/envelopes/{envelopeId}/recipients
{
"signers": [
{
"recipientId": 2,
"email": "newsigner#acme.com",
"name": "New Signer"
}
]
}
To Add tabs to the new recipient, use the CreateEnvelopeRecipientTabs api. Make sure you specify the recipientId correctly in the Url.
POST /v2/accounts/{accountId}/envelopes/{envelopeId}/recipients/{recipientId}/tabs
{
"signHereTabs": [
{
"documentId": "1",
"pageNumber": "1",
"xPosition": "120",
"yPosition": "120",
}
]
}
