01 / What volume changes

A sale week costs servers, not a fee per minute

No per-minute platform fee

Self-host the BSD-2 code and a busy week adds no platform charge. Servers, model keys and phone minutes still cost.

Concurrency you set

Self-hosted Dograh runs 10 calls at once by default. Raise it with DEFAULT_ORG_CONCURRENCY_LIMIT before your peak days.

Your order system, live

HTTP API tools read and write orders during the call. There is no built-in Shopify connector; the tool calls Shopify's API, directly or through n8n.

Overflow at your carrier

A call over the limit is rejected at once, not queued. Send busy calls to your team or a recorded message at the carrier.

02 / How it works

Verify, read, then write back once

Example
A shopper calls on sale daythe agent checks the order numberreads the order livewrites the change back
01 · Verify

Find the order, then check the caller

Pre-Call Data Fetchlooks up the number as the call connects

It returns a short order summary. The agent names nothing until the order number and postcode match.

→ A phone number finds an order but proves nothing

02 · Read

Answer from the order as it is now

HTTP API toolasks your order system mid-call

Status, stock and return eligibility come from your system, and the agent says only what came back.

→ If the lookup times out, offer a callback

03 · Write

Write each change back once

Preset Parameterthe call's ID rides with every write

An address fix or return request carries workflow_run_id, so your system ignores a repeat. A Webhook node posts the outcome after the call.

→ Write notes to your helpdesk before any transfer

04 / Before peak week

Check these before your biggest sale

  1. Limit set for the peakDEFAULT_ORG_CONCURRENCY_LIMIT matches your busiest day. On Dograh Cloud, ask Dograh for more than 10.
  2. Overflow route liveYour carrier sends calls over the limit to staff or a recorded message.
  3. Servers sizedYour servers and carrier set the real ceiling; test a burst of calls first.
  4. Slow lookups handledWhen the order API is slow, the agent offers a callback instead of guessing.
  5. No card numbers by voiceYour own system sends the payment link by text or email. Transcripts keep every word.

Questions
Does Dograh connect to Shopify?+

Through Shopify's API. There is no built-in Shopify connector; an HTTP API tool reads and writes orders during the call, directly or through n8n.

How many calls can run at once?+

10 by default. Self-hosted, raise it with DEFAULT_ORG_CONCURRENCY_LIMIT; your servers and carrier set the ceiling. On Dograh Cloud, contact Dograh for more.

What happens when every line is busy?+

The next inbound call is rejected at once, with no queue. Set an overflow at your carrier so those callers reach your team or a recorded message.

Is there a per-minute fee?+

Not when self-hosted. You still pay for servers, model keys and phone minutes. Dograh Cloud has a 1¢-a-minute platform fee.

Where are recordings and transcripts kept?+

Every call is recorded and transcribed. Self-hosted, both stay on your servers. Transcripts are not redacted, so never ask callers for card numbers or passwords.

Can the agent make abandoned-cart calls?+

Only to shoppers with prior express written consent on file, since a cart call is generally telemarketing in the US. This is not legal advice.

Point one test number at a real order lookup.

Self-host in one command, or start on Dograh Cloud.
