Skyvern API Integration – Callback & TOTP Issues in callin.io Workflow

I’m developing a callin.io automation that interfaces with Skyvern API to streamline job applications. The process involves extracting job postings from RSS Feeds, saving them in Airtable, submitting applications through Skyvern, and anticipating a callback with a response to update Airtable.

Furthermore, certain job platforms necessitate 2FA authentication, and I need Skyvern to retrieve the TOTP (one-time passcode) from my email.

Current callin.io Workflow

Email Trigger (IMAP): Captures emails that might contain OTP codes.

Code Node: Extracts the TOTP (if available) and forwards the entire email content to Skyvern.

HTTP Request to Skyvern: Transmits job application details and TOTP when required.

Respond to Webhook: (For Skyvern’s callback response). Expected to update Airtable.

Challenges I’m Encountering

Skyvern Callback Not Updating Airtable

• I configured a Webhook + Respond to Webhook to receive Skyvern’s response.
• However, Airtable is not being updated.
• It’s unclear whether Skyvern is sending a response or if callin.io is failing to process it.

TOTP Code Not Being Sent to Skyvern or Not Received

• Skyvern requires a TOTP Identifier to associate the OTP request with the correct workflow.
• I’m setting "totp_identifier": "myemail@example com" in the HTTP request, but Skyvern doesn’t appear to be capturing the OTP from my emails.
• Uncertain if my Code node is correctly extracting and transmitting the OTP.

Troubleshooting Steps Taken

Debugging the Skyvern Response by implementing Respond to Webhook.

Verifying the Skyvern HTTP request response.

Ensuring the 2FA Identifier aligns with the email address receiving OTPs.

Modifying the Code Node to transmit both email content and OTP (if found).
