Rates Task

Rates Task

Background job to manage ratedeck DB.

!!! note Only super admin can use this module.

About rates

Rates are stored in a database named after the ratedeck_id attribute. This defaults to ratedeck if not supplied.

An account can be assigned a ratedeck; if no ratedeck is assigned, the default ratedeck database is used. The account will be queried first, then the reseller, before selecting the default ratedeck.

Fields

NameDescriptionRequired
account_idreseller’s account (see first below)
descriptiondescription for rate
directiondirection of call leg (“inbound”, “outbound”), if not set - rate matches both directions
iso_country_codeISO 3166-1 code for prefix’s country
prefixprefix for match DID numbertrue
pvt_rate_costinternal rate cost, used for weight calculation
pvt_rate_surchargeinternal rate surcharge
rate_costper minute costtrue
rate_incrementbilling “steps” for rate
rate_minimumminimum call duration
rate_nameshort name for rate, if this field not set it will be generated from prefix, iso_country_code and direction fields
rate_nocharge_time“free” call time, if call duration less then this value (seconds), then call not charged
rate_surchargecharge amount on connect (answer)
rate_versionrate version
ratedeck_idratedeck name, assigned to account via service plan
weightwhen found several rates with same prefix, used rate with higher weight. If not set - calculated from prefix length and rate_cost (pvt_rate_cost)
caller_id_numbersstring of caller id prefixes separated by ”:“. For ex.: 441:442:443 It will be converted into [”^\+?441.+$”, ”^\+?442.+$”, ”^\+?443.+$“]
routesstring of either a single route ”^\+?44.+$” or a json array string ’[”^\\+?123$”,”^\\+?456$”]’

CSV files for all actions use the same list of fields. Names of fields match the names of keys in the CouchDB rate document.

!!! note For import and delete actions, value of account_id from CSV file will be ignored, value for this field is taken from task Account-ID .

!!! note options field can not be defined via CSV file (because its values are lists).

routes is automatically generated from prefix as the default or the json decode fails to parse the json array. Example: prefix 380 generates routes - ["^\\+?380.+$"].

Actions

Import

Import rates from CSV.

First, query the tasks API to learn what fields must be present in your CSV:

curl -v \
-H "X-Auth-Token: {AUTH_TOKEN}" \
'http://{SERVER}:8000/v2/tasks?category=rates&action=import'
{
    "data": {
        "tasks": {
            "rates": {
                "import": {
                    "description": "Bulk-import rates to a specified ratedeck",
                    "doc": "Creates rates from file",
                    "expected_content": "text/csv",
                    "mandatory": [
                        "prefix",
                        "rate_cost"
                    ],
                    "optional": [
                        "account_id",
                        "caller_id_numbers",
                        "carrier",
                        "description",
                        "direction",
                        "internal_rate_cost",
                        "iso_country_code",
                        "options",
                        "rate_increment",
                        "rate_minimum",
                        "rate_name",
                        "rate_nocharge_time",
                        "rate_suffix",
                        "rate_surcharge",
                        "rate_version",
                        "ratedeck_id",
                        "routes",
                        "weight"
                    ]
                }
            }
        }
    }
}

You can see prefix and rate_cost are mandatory fields and must be in the CSV header line. You can also name columns after the optional fields.

!!! note The direction field defaults to both inbound and outbound, meaning calls in and out will be rated accordingly. Alternatively, you can create a direction column in your CSV to specify the direction.

  • Create the task (upload the ratedeck):
curl -v -X PUT \
-H "X-Auth-Token: {AUTH_TOKEN}" \
-H "Content-type: text/csv" \
--data-binary @rates.csv \
'http://{SERVER}:8000/v2/tasks?category=rates&action=import'
{
  "auth_token": "{AUTH_TOKEN}",
  "data": {
    "_read_only": {
      "account_id": "{ACCOUNT_ID}",
      "action": "import",
      "auth_account_id": "{ACCOUNT_ID}",
      "category": "rates",
      "created": 63693042154,
      "id": "{TASK_ID}",
      "status": "pending",
      "total_count": 5
    }
  },
  "node": "{NODE_HASH}",
  "request_id": "{REQUEST_ID}",
  "status": "success",
  "timestamp": "{TIMESTAMP}",
  "version": "4.2.29"
}
  • Start the task (begin importing rates):
curl -v -X PATCH \
-H "X-Auth-Token: {AUTH_TOKEN}" \
'http://{SERVER}:8000/v2/tasks/{TASK_ID}'
{
  "auth_token": "{AUTH_TOKEN}",
  "data": {
    "_read_only": {
      "account_id": "{ACCOUNT_ID}",
      "action": "import",
      "auth_account_id": "{ACCOUNT_ID}",
      "category": "rates",
      "created": 63693042154,
      "id": "{TASK_ID}",
      "node": "{VM}@{HOSTNAME}",
      "start_timestamp": 63693042179,
      "status": "executing",
      "total_count": 101914
    }
  },
  "node": "{NODE_HASH}",
  "page_size": 1,
  "request_id": "{REQUEST_ID}",
  "revision": "automatic",
  "status": "success",
  "timestamp": "{TIMESTAMP}",
  "version": "4.2.29"
}

!!! note If the rate exists already (based on prefix, iso_country_code, and rate_suffix if present), it will be updated with the new value(s) in the CSV.

  • Query the task’s status:
curl -v -X GET \
   -H "X-Auth-Token: {AUTH_TOKEN}" \
   'http://{SERVER}:8000/v2/tasks/{TASK_ID}'

When data.status changes from executing, the task is completed.

Once the rate import is done, check out the rates API to see how to rate a DID via the API.

!!! note By default, there is a generous pause built into the system to avoid overloading the system. You can speed up task processing by decreasing the pause, in milliseconds (at the expense of more database load): sup kapps_config set_default tasks wait_after_row_ms 100

Sample CSV

As noted before, query the API to see what fields must be defined and what fields are optional:

curl -v \
-H "X-Auth-Token: {AUTH_TOKEN}" \
'http://{SERVER}:8000/v2/tasks?category=rates&action=import'
{
    "data": {
        "tasks": {
            "rates": {
                "import": {
                    "description": "Bulk-import rates to a specified ratedeck",
                    "doc": "Creates rates from file",
                    "expected_content": "text/csv",
                    "mandatory": [
                        "prefix",
                        "rate_cost"
                    ],
                    "optional": [
                        "account_id",
                        "caller_id_numbers",
                        "carrier",
                        "description",
                        "direction",
                        "internal_rate_cost",
                        "iso_country_code",
                        "options",
                        "rate_increment",
                        "rate_minimum",
                        "rate_name",
                        "rate_nocharge_time",
                        "rate_suffix",
                        "rate_surcharge",
                        "rate_version",
                        "ratedeck_id",
                        "routes",
                        "weight"
                    ]
                }
            }
        }
    }
}

The CSV must then define a header row with at least the mandatory fields defined.

"prefix","rate_cost","rate_name"
1,0.1,"US/Canada Default"
1415,0.05,"San Francisco"

Prefixes will match against the E164 number with the + stripped. Longest prefix matched wins.

Any fields not in the mandatory or optional list will be ignored. Order of the columns is irrelevant.

Export

Export all rates into CSV.

  • Start the export
curl -v -X PUT \
   -H "X-Auth-Token: {AUTH_TOKEN}" \
   'http://{SERVER}:8000/v2/tasks/?category=rates&action=export'
{
    "auth_token": "{AUTH_TOKEN}",
    "data": {
        "_read_only": {
            "account_id": "{ACCOUNT_ID}",
            "action": "export",
            "auth_account_id": "{AUTH_ACCOUNT_ID}",
            "category": "rates",
            "created": 63652613701,
            "id": "{TASK_ID}",
            "status": "pending"
        }
    },
    "request_id": "{REQUEST_ID}",
    "revision": "undefined",
    "status": "success"
}
  • Start the export task:
curl -v -X PATCH \
-H "X-Auth-Token: {AUTH_TOKEN}" \
'http://{SERVER}:8000/v2/tasks/{TASK_ID}'
  • Save the CSV

Once the task has completed, save the CSV locally:

curl -v -X GET \
   -o export.csv
   -H "Accept: text/csv"
   -H "X-Auth-Token: $AUTH_TOKEN"
   'http://{SERVER}:8000/v2/tasks/{TASK_ID}?csv_name=out.csv'

Delete

Delete rates for prefixes in CSV file. prefix is a mandatory field.

The rate will be deleted only if all defined fields in CSV file match the appropriate keys in rate document. An undefined field in CSV file means “match any”.
