// Kick off a verification for a new virtual address customer
const res = await fetch('https://api.colleckt.io/v1/verifications', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.COLLECKT_KEY}`,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    customer_id: 'cus_4JH2a1',
    cmra_id:     'cmra_anchor_01',
    requires:    ['photo_id', 'proof_of_address', 'form_1583'],
    submit_to_usps: true
  })
});

const { id, hosted_url } = await res.json();
// → redirect customer to hosted_url to complete KYC

“Before Colleckt, our 1583 backlog was the single biggest drag on new-customer activation. We cut verification turnaround from five business days to the same afternoon, with an audit trail our compliance team can actually sign off on.”
