# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

#  Send the following request:

# $ curl -X GET https://api.ibanity.com/xs2a/financial-institutions \
# --cert certificate.pem \
# --key private_key.pem \
# -H 'Signature: keyId="75b5d796-de5c-400a-81ce-e72371b01cbc",created=1599659223,algorithm="hs2019",headers="(request-target) digest (created) host",signature="BASE64(RSA-SHA256(SIGNING_STRING))"' \
# -H 'Digest: SHA-512=beDaRguyEb8fhh5wnl37bOTDtvhuYZyZNkTZ9LiC9Wc='

# Ibanity provides the certificate + private key in PFX format.  This example will use the .pfx instead of the pair of PEM files.
# (It is also possible to implement using Chilkat with the PEM files, but PFX is easier.)
