Frequently Asked Questions

Common questions about API for Ninja Forms

JSON, CSV, XLSX (Microsoft Excel), PDF, XML, and NDJSON/JSONL formats are supported.

Use cursor pagination with ?since_id={last_synced_id}&order=asc. Your application only receives new submissions created since the last sync.

Navigate to Settings > NF API Keys in your WordPress dashboard, check "Enable Response Payload Encryption", select your cipher strategy (AES-256-GCM, AES-128-GCM, or Sodium Secretbox), and generate a key. Keep your secret decryption key safe.

Binary files exported with encryption enabled are saved with a .enc file extension (e.g., form-1-submissions-encrypted.pdf.enc). Because the file content consists of raw encrypted bytes, attempting to open the file directly in Adobe Reader or Microsoft Excel without decrypting it first will report a corrupted file error. The .enc extension clearly indicates that the file must be decrypted using your secret key first.

Read the binary body and HTTP response headers (X-Crypto-IV, X-Crypto-Tag): `php $response = wp_remote_get('https://example.com/wp-json/nf-submissions/v1/form/1?format=pdf', [ 'headers' => ['Authorization' => 'Bearer YOUR_API_KEY'] ]); if ( is_wp_error( $response ) || 200 !== wp_remote_retrieve_response_code( $response ) ) { exit( 'Download failed or unauthorized.' ); } $headers = wp_remote_retrieve_headers($response); $binary_key = hex2bin('YOUR_DECRYPTION_KEY'); $iv = base64_decode($headers['x-crypto-iv']); $tag = base64_decode($headers['x-crypto-tag']); $decrypted_pdf = openssl_decrypt( wp_remote_retrieve_body($response), 'aes-256-gcm', $binary_key, OPENSSL_RAW_DATA, $iv, $tag ); file_put_contents('submissions.pdf', $decrypted_pdf); `

Parse the JSON response envelope and decrypt using OpenSSL: php $json = json_decode($response_body, true); if (!empty($json['encrypted'])) { $binary_key = hex2bin('YOUR_DECRYPTION_KEY'); $plaintext = openssl_decrypt( base64_decode($json['ciphertext']), $json['algorithm'], $binary_key, OPENSSL_RAW_DATA, base64_decode($json['iv']), base64_decode($json['tag']) ); $data = json_decode($plaintext, true); }

No. Text feeds use lightweight JSON structures and binary feeds use raw stream transmission to ensure high throughput and low memory usage.
