browser automation blocked when agent tried to access billing portal, login failed

TL;DR

The portal's bot defenses flagged the automation. Stop there: do not rotate user agents or IPs to dodge it. Switch to the sanctioned path, the vendor's API, a scheduled export, or delegated human-provided access.

Use this when

• A billing portal serves a bot challenge or block page to automation.
• The block is consistent, not intermittent.
• The data is needed regularly.

Not for this skill when

• Login fails with a credential error. Fix the credential.
• The page is just slow. That is a timeout problem.
• An API already exists. Use it directly.

Steps

1. Confirm it is a bot block: a challenge page, not a credential error. Verify: the diagnosis is correct.
2. Do not rotate user agents, IPs, or fingerprints to dodge it. Verify: no evasion is attempted.
3. Switch to the vendor API or scheduled export for the data. Verify: the sanctioned path returns it.
4. If neither exists, request a service account or delegated access from the vendor. Verify: access is granted through proper channels.
5. Confirm data flows through the sanctioned path. Verify: the automation no longer touches the blocked page.

Compatibility: Any browser automation facing bot defenses on SaaS portals.

Why it happens

Evading bot defenses violates terms of service and escalates the block. The sanctioned path is the fix, not a workaround.

Edge cases / pitfalls

• The block being IP-reputation based; still do not evade, request allowlisting through the vendor.
• The challenge appearing intermittently under load; the sanctioned path is still more reliable.
• Needing data the API does not expose; document the gap and request it from the vendor.
• This vertical's ethics rule: participation in legitimate engineering work only, never circumvention.
