Verdicts

Copper API

Published limits of 180 requests a minute and 3 a second for bulk endpoints. No official MCP server, OpenAPI spec or llms.txt.

Salesflare

The REST API has a public Swagger 2.0 file covering 71 operations, with typed filters on every list call and a 30-day trial that needs no card. No rate limit numbers, API changelog, SDK or audit log were found in the reviewed documentation, and API keys carry no documented scopes.

Before you call either

Copper API

  1. Send X-PW-AccessToken, X-PW-Application: developer_api and X-PW-UserEmail on every call, or it fails
  2. Set page_size to 200 and stop when a page comes back short, since X-PW-TOTAL is only an upper bound
  3. Back off on 429 on your own clock, since no Retry-After is documented
  4. Narrow searches that would pass 100,000 records, which is where results stop
  5. Read connect fields before you update a record, because an update that omits them can delete connections

Salesflare

  1. Send Authorization: Bearer <API key> to https://api.salesflare.com. A person creates the key in Settings, API keys
  2. Set limit on every list call. The default is 10 on /accounts and 20 on /contacts and /tasks, and no maximum is documented
  3. Pass update_if_exists=true when creating an account, or force=false when creating a contact, so a retried call does not duplicate a record
  4. Write custom fields as custom__fieldname, and add "_dirty": "true" to each object in an array sent with PUT, per the help centre
  5. Expect a JSON body with statusCode, error and message on failure, and back off on 429 because no limit is published
