"The bot says my bank is blocking without offering a solution." "The AI doesn't know that I can split the cart." "Chatbot promises to raise the card limit." Three failures where a poorly calibrated payment limit bot abandons a large cart or hallucinates a bank unblocking.
A payment limits e-commerce AI chatbot does not replace PAYLIM agents (#787). It reads PAYLIM-MAP, quotes card_limit_explain_copy, offers cart_split_policy_copy and alternative_methods_copy at checkout before B2B human handoff.
This guide #788 covers intents bot_paylim_*, flow PAYLIMbot and KPI paylim_bot. Companion bot to the PAYLIM playbook (#787). AI use case: tier 1 blocked cart options and splitting.
Summary
Why automate payment limits by bot at checkout?
"Card limit", "basket total too high for Klarna", and "bank limit reached" errors occur at the checkout payment step. A calibrated bot references the limit details, proposes splitting the basket, and suggests alternatives without promising a bank override or blaming the store.
What the tier 1 bot solves for payment limits
Limit explain: card_limit_explain_copy bank_limit_explain_copy LIMIT-CITE-BOT map
Cart split propose: cart_split_policy_copy SPLIT-CITE-BOT map
Alternative propose: alternative_methods_copy ALT-CITE-BOT map
BNPL max explain: bnpl_max_amount_copy map
Handoff escalate: #787 payload cart_amount payment_method
Limits block conversion for high-value baskets if poorly explained (Shopify, checkout abandonment 2026). Without a grounded bot, the AI routes the user to payment declined or BNPLDEC #785.
PAYLIMbot vs PAYLIM #787, BNPLDECbot #786, payment declined and anti-hallucination #123
Six contents, six distinct blocked increasing paths.
Quick Matrix
#788 PAYLIMbot: tier 1 bot installment options checkout embed
#787 PAYLIM : agents split escalate B2B corporate
BNPLDECbot #786 : refusal scoring BNPL distinct max basket ceiling
Card payment declined : 3D Secure fraud decline distinct threshold limit
SPLITPAYbot #776 : merchant direct debits distinct card limit
Anti-hallucination #123 : alternative limits = map whitelist only
Pipeline: #788 bot installment options tier 1 → #787 agents split escalate B2B.
Which bot_paylim_* intents should be configured?
Eight bot payment limit intents mapped to paylim_* typologies #787.
Eight bot_paylim intents
bot_paylim_card : card_limit_explain_copy LIMIT-CITE-BOT map
bot_paylim_bank : bank_limit_explain_copy LIMIT-CITE-BOT map
bot_paylim_bnpl_max : bnpl_max_amount_copy map

bot_paylim_handoff : escalate B2B → PAYLIM787-HANDOFF-BOT
Tier 1 auto : card bank split alternative if PAYLIM-MAP active + guardrails LIMIT-CITE-BOT NO-BANK-UNLOCK-BOT.
bot_paylim_handoff corporate bulk → agents #787 payload cart_amount card_type.
How do I consume PAYLIM-MAP #787?
The bot reads PAYLIM-MAP #787: paylim_program_id, card_limit_explain_copy, bank_limit_explain_copy, bnpl_max_amount_copy, cart_split_policy_copy, alternative_methods_copy, increase_limit_steps_copy, corporate_card_copy, bnpldec_reroute_copy, declined_reroute_copy.
