EasyPost does not provide a public Postman collection; however, here is an example of a shipment Postman body (raw) that could be used. You can adjust the values, actions, objects, etc to your needs.
Using the following, you shouldn't need to pass any headers. You'll pass your API key under the username
field with the Basic Auth
authorization type.
{
"shipment": {
"to_address": {
"id": "adr_123..."
},
"from_address": {
"id": "adr_123..."
},
"parcel": {
"id": "prcl_123..."
},
"carrier_accounts": {
"id": "ca_123..."
},
"options": {
"address_validation_level": "0"
}
},
"format": "json",
"controller": "shipments",
