View OpenAPI Spec

iSendPro is a French SMS gateway run by CALL ON IT covering single and bulk SMS delivery, HLR lookup, contact directory management, blocklist administration, and subaccount provisioning. The 14 endpoints support sending one-shot SMS via POST /sms, broadcasting through POST /smsmulti, retrieving campaign recaps, validating numbers via HLR, generating short links, and metering character counts before send. Authentication is a per-account keyid passed in the request body alongside an IP allow-list configured in the iSendPro dashboard.

Use Cases

Patterns agents use API iSendPro API for, with concrete tasks.

★ Transactional SMS delivery for French ecommerce

Send order confirmations, delivery alerts, and OTP codes to French and European customers through POST /sms. iSendPro routes via tier-1 carriers and supports custom alphanumeric sender IDs where local regulation allows. Integration takes a couple of hours including HLR validation and credit-check wiring.

Send the message 'Votre commande #4231 est expediee' to phone number 33612345678 with sender ID 'BOUTIQUE'

Bulk marketing campaign with opt-out enforcement

Run a marketing SMS broadcast against a contact directory while honouring blocklisted numbers. The agent posts the recipient list to POST /smsmulti, then queries POST /campagne for the per-message status. Numbers added to the blocklist via POST /setlistenoire are filtered out automatically by iSendPro before billing applies.

Broadcast the message 'Soldes -30%' to the directory 'newsletter-fr' and skip numbers on the blocklist

Number validation pipeline before campaign send

Reduce wasted SMS credit by running an HLR lookup against every recipient via POST /hlr before broadcasting. Invalid or unreachable numbers are removed from the campaign so the spend lands only on numbers with active SIMs. Combined with the POST /comptage character-count check, the agent can predict campaign cost to within a few percent.

For each number in the supplied CSV, run POST /hlr and write back active or inactive status

AI agent customer support SMS notifications

An AI customer support agent can fire SMS alerts during workflow handoffs without operating a separate SMS integration. Through Jentic the agent searches for 'send a French SMS' and the matching iSendPro operation is loaded with the keyid already injected from the vault. Lets the agent close the loop with the customer over the channel they actually read.

After a refund is approved, send the customer at 33612345678 the message 'Remboursement approuve, sous 3 jours ouvres'

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

iSendPro keyid values are stored encrypted in the Jentic vault. Agents receive scoped execution tokens — the raw keyid never enters the agent context, which matters because iSendPro charges per SMS sent.

Intent-based discovery

Agents search by intent (e.g. 'send a French SMS' or 'validate phone number HLR') and Jentic returns the matching iSendPro operation with its body schema — including the often-overlooked sms array structure.

Time to first call

Direct iSendPro integration: 4-8 hours to wire the JSON-in-body keyid pattern, IP allow-list, HLR pre-flight, and campaign recap polling. Through Jentic: under 30 minutes — search, load schema, execute.

FAQs

Specific to using API iSendPro API through Jentic.

What authentication does the iSendPro API use?

iSendPro authenticates with a per-account keyid sent inside the JSON request body, alongside an IP allow-list configured in the iSendPro dashboard. The keyid is generated under the 'mon compte' panel of the iSendPro account. Through Jentic the keyid is held in the vault and injected at request time.

Can I send bulk SMS in a single call?

Yes. POST /smsmulti accepts a list of recipients in one request and returns a per-message status array. For very large lists the request can be split into batches; recap retrieval through POST /campagne reconciles the status of each message later.

What are the rate limits for the iSendPro API?

Hard rate limits are not declared in the spec. iSendPro applies a fair-use ceiling tied to the account's monthly volume tier, with the IP allow-list serving as the practical gating mechanism. Confirm the account-level throughput before driving very large bursts.

How do I validate a mobile number before sending through Jentic?

Search Jentic with the query 'validate French mobile number' or 'HLR lookup', load the POST /hlr operation, and execute it with the recipient phone number. The response indicates whether the number is active and which operator is hosting it.

Is the iSendPro API free?

iSendPro is a paid service. New accounts can request a test credit on application; production usage is billed per SMS with volume tiering. Check current pricing on the iSendPro website before forecasting campaign cost.

Does iSendPro support short links inside SMS?

Yes. POST /shortlink generates a trackable short URL that can be embedded in the SMS body. Click counts are then surfaced through the campaign recap endpoint.
