Authentication with API Key

To access the API, an API key is required.

1

Obtaining the API Key

The API key is provided after successful onboarding.

2

Using the API Key in the request

The API key must be included in the header of each request.

Example:

curl --location 'https://api.multisource.ch/v2/search/calllookup?number=0791234567' \
--header 'Auth-Key: <API-KEY>'
3

Managing the API Key

  • The API key is a security-sensitive credential and must be handled confidentially.

  • If a key is compromised or becomes invalid, it can be renewed or revoked at any time.
