Plain HTTP calls will fail. The token is **stateless and expires after ~5 minutes**, so it must be computed fresh for each request.\n\n### Header format\n\n```\nX-WSSE: UsernameToken Username=\"<username>\", PasswordDigest=\"<digest>\", Nonce=\"<nonce_b64>\", Created=\"<timestamp>\"\n```\n\n### Fields\n\n| Field | Description |\n|---|---|\n| `Username` | The username assigned during onboarding. |\n| `Nonce` | A Base64-encoded random hex string (≥ 32 hex characters). |\n| `Created` | Current UTC timestamp in ISO 8601: `YYYY-MM-DDTHH:MM:SSZ`. |\n| `PasswordDigest` | `Base64( SHA-1( nonce_bytes ∥ created_bytes ∥ secret_bytes ) )` — SHA-1 **binary** digest, then Base64. |\n\n### Algorithm (step-by-step)\n\n1. Generate a random nonce: at least 32 lowercase hexadecimal characters (e.g. `d36e3162829ed4c89851497a717f0001`).\n2. Get the current UTC timestamp as an ISO-8601 string (e.g. `2026-05-12T10:30:00Z`).\n3. Encode the nonce string as UTF-8 bytes, the timestamp as UTF-8 bytes, and the API secret as UTF-8 bytes.\n4. Compute `SHA-1( nonce_bytes + created_bytes + secret_bytes )`. The hash **must** be the raw binary digest (not hex).\n5. `PasswordDigest` = `Base64( sha1_binary_digest )`\n6. `Nonce` = `Base64( nonce_utf8_bytes )`\n\n### Code samples\n\n**Python**\n```python\nimport base64, hashlib, os, binascii\nfrom datetime import datetime, timezone\n\ndef generate_xwsse(username: str, secret: str) -> str:\n    nonce = binascii.b2a_hex(os.urandom(16))          # 32 hex bytes\n    created = datetime.now(timezone.utc).strftime(\"%Y-%m-%dT%H:%M:%SZ\")\n    digest = base64.b64encode(\n        hashlib.sha1(nonce + created.encode() + secret.encode()).digest()\n    ).decode()\n    nonce_b64 = base64.b64encode(nonce).decode()\n    return f'UsernameToken Username=\"{username}\", PasswordDigest=\"{digest}\", Nonce=\"{nonce_b64}\", Created=\"{created}\"'\n```\n\n**JavaScript (Node.js)**\n```javascript\nconst crypto = require('crypto');\nfunction generateXWSSE(username, secret) {\n    const nonce = crypto.randomBytes(16);\n    const created = new Date().toISOString();\n    const digest = crypto.createHash('sha1')\n        .update(nonce)\n        .update(Buffer.from(created))\n        .update(Buffer.from(secret))\n        .digest('base64');\n    return `UsernameToken Username=\"${username}\", PasswordDigest=\"${digest}\", Nonce=\"${nonce.toString('base64')}\", Created=\"${created}\"`;\n}\n```\n\n**PHP**\n```php\nfunction generateXWSSE(string $username, string $secret): string {\n    $nonce = bin2hex(random_bytes(16));          // 32 hex chars\n    $created = gmdate('Y-m-d\\TH:i:s\\Z');\n    $digest = base64_encode(sha1($nonce . $created . $secret, true));\n    return sprintf('UsernameToken Username=\"%s\", PasswordDigest=\"%s\", Nonce=\"%s\", Created=\"%s\"',\n        $username, $digest, base64_encode($nonce), $created);\n}\n```\n\n### Environments\n\n| Environment | Base URL |\n|---|---|\n| Demo (testing) | `https://api-demo.ibanfirst.com/api` |\n| Live (production) | `https://api.ibanfirst.com/api` |\n\n### Forbidden characters in input fields\n\nThe following characters are rejected in route parameters, query parameters, and JSON bodies: `&` `<` `>` `%` `?` `\\` `/` `|`"

        Algorithm:

        1. Generate a random nonce: ≥ 32 lowercase hex characters.

        2. Get current UTC timestamp in ISO 8601: `YYYY-MM-DDTHH:MM:SSZ`.

        3. Compute `PasswordDigest = Base64( SHA-1( nonce_bytes + created_bytes + secret_bytes ) )` — SHA-1 over the raw UTF-8 bytes concatenated in that order, result must be the binary digest before Base64 encoding.

        4. Compute `Nonce = Base64( nonce_utf8_bytes )`.
