Changes the reply or the added keywords of a rule you created. Bird's defaults cannot be changed. To replace one, create a rule with the same operation and country and yours takes precedence. What the rule applies to is fixed once created, so this changes the reply and the keywords only. Replaces the extra keywords this rule matches, on top of the ones Bird ships. Send an empty array to keep Bird's keywords only. Omit to leave the current ones unchanged. Replaces the message sent back when a keyword matches. Set it to null together with `confirmed_self_managed` to switch the auto-reply off. Omit to leave it unchanged. Set this with `reply: null` to confirm you send this reply from your own system. Required to switch the auto-reply off, and rejected when a reply is given. Identifier of a keyword rule. An `sks_` id is one of Bird's defaults, which you can read but not change; an `skw_` id is a rule your workspace created. Whether the rule is one of Bird's defaults (`system`) or one your workspace created (`workspace`). A `workspace` rule takes precedence over Bird's default for the same country, so it is how you replace a reply without losing the keywords Bird ships. Possible values: `system`, `workspace` What Bird does when an inbound message matches one of the rule's keywords. "stop" unsubscribes the sender, "start" resubscribes them, and "help" replies with your support information. Those three are what carriers and regulators expect a number to honour, so Bird ships keywords for them wherever its catalogue covers the country, and you cannot change what they do. "custom" carries no built-in behaviour: it matches keywords you choose and sends the reply you write, which is how campaign keywords like PIZZA are handled. Open enum: additional operations may be added over time, so treat an unrecognized value as a future operation rather than an error. Possible values (may grow over time): `stop`, `start`, `help`, `custom` The country the rule applies in, as an ISO 3166-1 alpha-2 code. A rule for `NL` covers messages received on your Dutch numbers, and messages from a subscriber whose own number is Dutch whichever of your numbers they text. A rule for the country a message arrives in wins over a rule for the country its sender is in, and both win over Bird's own keywords; `number` confines a rule to one number. Null means the rule applies worldwide, which is allowed for `custom` operations only. The language this rule covers, in countries where Bird ships keywords in more than one. Canada has separate English and French rules, so a Canadian rule names which one it replaces and the other keeps Bird's reply. Null in countries with a single set. Narrows the rule to one of your numbers in E.164 format, instead of every number you hold in the country. Null means it applies to all of them. The keywords this rule adds. For one of Bird's defaults this is the full set Bird ships. For a rule you created it is only what you added on top. It never restates or removes Bird's keywords, so `effective_keywords` is what actually matches. Every keyword that matches this rule: Bird's keywords for the same operation, country and language, plus the ones you added. This is what an inbound message is compared against. Keywords Bird adds later join it without you changing anything. The message sent back when one of the keywords matches. Null when the auto-reply is switched off, which `reply_disabled_at` distinguishes from a rule that has not been given one. Text appended to your reply that you cannot change: the rates and opt-out wording carriers require on a help response. Your reply is sent in front of it, and both count against the length a single message allows. Null when the operation carries none. When the auto-reply for this rule was switched off, or null if it is on. Switching it off records that you send this reply from your own system, which is what Bird points to if a carrier asks why no reply went out. Whether what this operation does is fixed. When true you can change the reply but not the behaviour. An opt-out keyword always unsubscribes the sender, whichever rule matched it, because carriers and regulators require it. When the rule was created. When the rule was last changed. On one of Bird's defaults this is when Bird last changed the keywords or the reply for that country.
